Buying a House With a Private Well in Sussex County
The short answer
New Jersey's Private Well Testing Act requires a water test before closing on most homes with a private well. In Sussex County, the test covers the statewide list — bacteria, nitrate, iron, manganese, pH, VOCs, lead, arsenic, gross alpha, certain PFAS and other compounds — plus uranium. Results go to both buyer and seller, and the contract decides what happens if something fails.
If you're buying in Sussex County, there's a good chance the house has a private well. That isn't a problem — it just means you need to understand the water before you own it. Here's what the law requires, what the test covers, and how to handle results.
Does New Jersey require a well test when you buy a house?
Yes. The Private Well Testing Act (in effect since 2002) requires testing of a private potable well before closing on most real estate sales. Both the buyer and the seller must review the results. Testing is also required for certain rental properties.
The law is about testing and disclosure. It doesn't automatically require the seller to fix anything. That's handled in your contract.
What does the well test check for in Sussex County?
The state rule sets a list that applies everywhere in New Jersey, and adds a few parameters by county.
| Tested everywhere in NJ | Added in Sussex County |
|---|---|
| Total coliform bacteria (and E. coli if coliform is present) | Uranium |
| Nitrate | |
| Iron and manganese | |
| pH | |
| Volatile organic compounds (VOCs) | |
| Lead | |
| Arsenic | |
| Gross alpha (48-hour rapid test) | |
| 1,2,3-trichloropropane, ethylene dibromide, DBCP | |
| PFAS: PFNA, PFOA and PFOS |
Uranium is also required in Warren and Morris counties, among others. The test must be done by a state-certified laboratory.
What do results usually show?
Common issues in North Jersey wells include bacteria, hardness and iron or manganese (which affect taste, staining and appliances more than safety) and, in some areas, naturally occurring radioactive elements or arsenic. Many issues are treatable with the right equipment.
What matters is understanding:
- Is it a health issue or an aesthetic one? Iron staining is annoying; bacteria or arsenic over limits is a health concern.
- What's the fix and the ongoing cost? A UV system, a softener, a whole-house filter or point-of-use treatment each have different costs and maintenance.
- Is it one-time or recurring? A bacteria hit can sometimes be fixed by shock chlorination and a retest. Other issues need permanent treatment.
Your water treatment professional, not your agent, should recommend specific equipment.
What happens if the well test fails?
Your contract decides. Your attorney will usually negotiate terms during attorney review, such as:
- The seller installs treatment and provides a passing retest before closing
- The seller gives a credit so you can install the system you choose
- The price is adjusted
- If the issue is serious enough and the contract allows, the buyer can cancel
Get a quote from a water treatment company quickly, so the negotiation is based on real numbers.
What else should I check about the well?
The required test is about water quality, not the well itself. Ask about:
- Flow or yield. How many gallons per minute? Is it enough for your household?
- Well age and location. Where is it relative to the septic system and the driveway?
- Equipment. Pump age, pressure tank, existing treatment systems and service records.
- Well records. Some wells have a well record on file with the state that shows depth and construction.
How do I own a well home responsibly?
- Test periodically. Health officials recommend testing your well regularly after you move in, not just at sale. New Jersey also offers a state income tax deduction for private well testing — ask your tax preparer.
- Maintain treatment systems. UV bulbs, filters and softener salt aren't optional.
- Protect the wellhead. Keep chemicals, fuel and pet waste away from it.
The bottom line
A well is normal here. The buyers who get into trouble are the ones who treat the test as a box to check. Read the results, understand them, price in the fix and negotiate based on facts.

Frequently asked questions
Is well testing required when buying a house in New Jersey?
Yes, for most sales of property with a private potable well. The Private Well Testing Act requires testing before the title closes, and both buyer and seller must review the results.
What does the NJ well test check for in Sussex County?
The statewide parameters — including total coliform bacteria, nitrate, iron, manganese, pH, volatile organic compounds, lead, arsenic, gross alpha, certain PFAS (PFNA, PFOA, PFOS) and three additional compounds added in 2019 — plus uranium, which is required in Sussex, Warren and Morris counties among others.
What happens if the well water fails?
The law requires testing and disclosure, but your contract decides what happens next. Common outcomes are seller treatment, a credit, a price change or, in some cases, cancellation. Many issues are treatable.
Who pays for the well test?
It's negotiable and set in the contract. In practice, sellers often pay. Your attorney will confirm.
Should I also test the well's flow?
The required test is about water quality, not quantity. Many buyers also ask for a flow or yield test, especially for larger households. Discuss it with your inspector.
